Comment: Powerless dehumidifier (Score 1) 89

by John Bokma (#47468543) Attached to: Harvesting Energy From Humidity
I live in an area with high humidity (~80% / 25C) and am wondering how well this would work as a dehumifier that uses no electricity. The one we own is rated at 400 Wh. We often run in daily for 2+hrs. Also, if this is effective I can see other uses, like drying clothes. Or a small set up that can provide 2-3 liters of potable water/day.

Last 10 years? Make sure you don't buy garbage made by Whirlpool as it's made to fall apart in a very short time. This is the front of our gasrange after less than 5 years of careful use: http://toxicice.com/images/eng...

According to Whirlpool this is "normal wear and tear". Good luck using an oven if you can't even read the markings anymore

Aside: the "clock" doesn't even have battery backup. It's 80's technology but made to last way less long.

Comment: Perl programmer, using Emacs (Score 1) 359

I use Emacs, mostly. For editing files as root or over SSH I often use vi(m). I still want to switch to vim for all my editing for a few months, just to see if I can get used to it. Don't think I will convert to vim, but I think the only way to get used to an editor (and have non-biased opinion about it) is to use it for a few months (and RTFM, of course). On Windows, several years back, I used TextPad mostly.

A lot of best practices for Perl are good programming practices in general. Of course there are (plenty) of exceptions, but that's the case with other languages as well. One thing one wants to avoid is to program Python in Haskell or Pascal in C, for example.

As for hard to read (for a beginner) have a look at Haskell, for example.

Python's fame is that it "reads like pseudocode". That's nice, but utterly fails if a programmer has no good feel for algorithms. Pascal used to have the same fame. A few years back I had to reimplement a Pascal program into Perl. One of the pieces of code was 100+ lines. After some studying it turned out to be a variant of bubble sort. At the end few lines reversed the sort order (!). It could be replaced with a few lines of Perl. And no, not because I write short and cryptic code. The code could've been written way shorter in Pascal as well, even when implementing a sort manually.

If money can't buy happiness, I guess you'll just have to rent it.
